Can I make hardware changes to upgrade my Elitedesk 800 G3 SFF to Windows 11?

[ppksky]

I see by my PC Health Check that my CPU does not support Windows 11 and that I am missing TPM 2.0. I did some searching on the subject of TPM and found modules available to plug in, but I don't see any on eBay to support my computer and opening it up, I don't see any place for it to go. I would like to up grade my CPU, I have another post here asking if I can add a 9700 i7 CPU. Would that upgrade my system to support Windows 11?

Hi:

Unfortunately, there aren't any upgrades you can do to the PC to make it W11-capable.

The model series only supports the Intel 7th gen core processors and W11 requires Intel 8th gen or newer processors.

You can do a firmware upgrade for the TPM from version 1.2 to 2.0 by reading the guidance at the link below.

HP Desktops, Notebooks, and Workstations - HP TPM Configuration Utility With Windows 10 Anniversary ...

If you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2.

You have to use the version of the Rufus utility that I zipped up and attached in the discussion (v3.18).

If the in-place upgrade fails, you should be able to clean install W11 using the bootable W11 installation flash drive you made with Rufus.
